Construction and function
Operating elements
The SKF operating elements are available as accessories for the TFG and the SKF control
unit. If you have any questions, please consult the corresponding operating manuals for
these devices.
Function
A description of its function allows you to understand what the telescopic pillar and its
individual parts do.
Functional principles
The functional principle of the TFG telescopic pillar is based on a pulling or pushing force
for the movement of centric and excentric loads. A DC motor drives a lead screw via a
worm gear. A spindle nut, which is attached to the push tube, moves up and down on
the lead screw. The rotation direction is determined by the control unit and works on the
reverse polarity voltage principle. The built-in brake decelerates the movement or holds
the position at a standstill.
TFG 1..The telescopic pillar TFG 1.. is not equipped with a control unit and must be oper-
ated with a suitable SKF control unit and a SKF operating element.
TFG 5.., TFG 9..: The telescopic pillars TFG 5.. and/or TFG 9.. are equipped with mains
connection and an integrated control unit. A suitable SKF operating element can be con-
nected directly to TFG 5.., TFG 9...
Connections (a1)
❙ TFG 1.. Equipped with a cable with a DIN8 plug for a SKF control unit.
❙ TFG 5.., TFG 9.. Equipped with a mains connection and a connection for a SKF
operating element. With the corresponding options selected, the TFG 5.., TFG 9.. can be
energized (b4a, b4b, b4c) and operated (b3) via the final plate (a9)
Base plate (a2)
The base plate has 4 openings for one fastening screw each. Its purpose is to fasten the
pillar to the application.
Housing (a12)
The housing must not be removed.
Cover (a3)
The cover is protected with two fastening screws (a13) in accordance with IP30 and
must not be removed while in operation. The purpose of the cover is to protect the pillar
unit and the connections.
❙ TFG 1..: Located under the cover are the connections with the DIN 8 plug for a SKF
control unit, and the optional mains cable and operating element feed through.
❙ TFG 5.., TFG 9..: Located under the cover are the connections for the optional
mains cable feed through. The control unit housing has openings for the corresponding

L5312,1675D.0/10.10
Construction and function
Rim cover for outer and
middle tube (a5, a7)
The purpose of the rim covers for the outer and middle tubes is to protect the tubes and
to prevent the ingress of foreign matter, and they must not be removed under any cir-
cumstance.
Final plate (a9)
The application is fastened on the final plate. The push tube (b5) must also be attached
permanently with a fastening screw (opening for the fastening screw visible on position

Guide tube unit
The guide tube unit is made up of the outer tube (a4), the middle tube (a6) and the inner
tube (a8), and its purpose is to carry centric and excentric loads.
Drive unit
The permanent magnet motor is a 24 V DC motor that drives the lead screw via the
worm gear. The speed of the thrust depends on the load.
Worm gear
The worm gear drives the lead screw. It is driven via the permanent magnet motor.
Thermo-switch
❙ TFG 1..: Thermal overload must be prevented by the control unit, as the TFG 1..
does not have a thermo-switch.
❙ TFG 5.., TFG 9..: The thermo-switch in the control unit controls thermal and elec-
trical overload and switches off the permanent magnet motor in an emergency. The pil-
lar can not be operated again until the drive temperature has fallen below the switching
threshold.
Switching off in case of
overcurrent
❙ TFG 1..: It must be ensured that the control unit will switch off in case of overcur-
rent, as the TFG 1.. does not have this switch-off facility integrated.
❙ TFG 5.., TFG 9..: The control unit has a switch-off facility in the case of overcurrent
integrated which protects the pillar from overload.
Brake
The brake is attached to the lead screw, its purpose is to decelerate the lead screw and
to prevent a return movement.
Options and accessories
Options

TFG.
Please note: The entity doing the further processing must devise and install an
emergency stop switch or a separation from the mains supply on all poles.
CAUTION
Beware of electric shock due to a squashed cable. Ensure that ca-
bles cannot get pinched or damaged. Check that the mains voltage
corresponds to the nominal value on the type plate. Ensure that the
strain relief clamp and cabling are correct.
CAUTION
Beware of damage to the TFG caused by splashing or hose-directed
water. The telescopic pillar TFG is, in accordance with IP30, not
protected against splashing or hose-directed water. Exposure of
the TFG to splashing or hose directed water must be prevented at
all times.
• If required, protect your telescopic pillar with appropriate
protective measures.

Installation and initial start-up
Power supply
The telescopic pillar TFG runs solely on electricity. Observe the connection values in the
appendix of this manual (chapter Equipment and operating data, page 33).
Installation and connections
Installing the telescopic pillar TFG on other elements (equipment carrier, etc.) involves
taking into account special requirements of different applications.
The telescopic pillar TFG attaches to two elements via the final and base plate and/or,
optionally, via adapter plates.
The following sections show how to set up and align the telescopic pillar, as well as the
interfaces and connections TFG.
Set-up and adjustment
In setting up and aligning the telescopic pillar, TFG the following points must be
observed. For the installation, you will require:
■8 M6 fastening screws, property class 10.9
■1 M10 fastening screw, property class 10.9
Make sure that
■the telescopic pillar TFG is attached to elements of the application on both sides,
■all attachment points are securely screwed to the application,
■the elements are fully aligned and seated at the top and at the bottom,
■the acting force does not impact the guide tubes with inadmissibly high values, as
side-impacting forces that are too high can destroy the pillar,
■the actuator is not obstructed in any way in the entire lifting area.
■the cables are not pinched or caught or subject to tension stress.
■If the TFG telescopic pillar is installed in horizontal position, a maximum torque
(Mb) of 500 Nm must not be exceeded at the bottom mounting plate.
■If necessary, the outer tube must be supported by suitable measures (see Fig. 5-
2, page 22).
■In the case of higher eccentric loads, please contact your local SKF representative
(Manufacturer address, page 6).
